Installed bazzite using dual boot guide now this
I'm getting the error "Ostree admin istutil set-kargs resume=<GUID> rhgb quiet root=<GUID>". Not sure what to do now

Solution
I'd try install Fedora Kinoite (assuming that you want Bazzite KDE) and then just rebase to bazzite. The rebase instructions are on the right side of the screen when you downloading the ISO.
